Which term describes an imaginary line that allows for sideward rotation in the body?

The term that describes an imaginary line allowing for sideward rotation in the body is the frontal axis. This axis runs horizontally from side to side, facilitating movements such as lateral flexion, abduction, and adduction, which occur in the frontal plane. When the body rotates around this axis, it enables effective side-to-side movements.

In contrast, the sagittal axis runs from front to back and is primarily involved in forward and backward movement, while the vertical axis, which runs from top to bottom, facilitates rotational movements around the body’s center. The frontal plane refers to the vertical plane that divides the body into front and back sections but does not describe the axis of movement itself. Understanding these concepts helps clarify how different movements relate to the axes of rotation and planes of motion in physical education.
